Abstract
Raw cotton contains various type of trash and most of the impurities are removed during the spinning process but still the
cotton fabric coming from the weaving or knitting process always contains some impurities. Some time cotton fabric gets the
oil, stains and coloured materials which affect the quality of dyed fabric. Bleaching is a process that eliminates unwanted
coloured matters from the fibres, yarn and fabrics. A bleaching agent is a material that lightens or whitens a substrate through
chemical action. Hydrogen peroxide is by far the most commonly used oxidative bleaching agent for cotton and its blends,
accounting for more than 90 percent of all the bleaching agents. The use of activators to enhance the bleaching performance
of hydrogen peroxide for cellulosic materials has gained popularity now a day. In this context the main objectives of this
paper are to study the influence of different bleaching activators on cotton fabric and to give implications for textile
extension. The results indicate that the activators with different concentrations, along with different concentrations of
hydrogen peroxide (H2O2) have significant influence on the bleaching performance of cotton fabric.
